Automatic FM setup
When your radio is first connected to a power supply (batteries or mains)
or after a power failure (when backup batteries are not installed), the
Auto setup will automatically search the FM waveband and store
stations in presets.
1. Install batteries or connect to mains (see page 6). Your radio will
show start searching the FM waveband.
2. Your radio will automatically switch off and return to time display
when setup is complete. (Setting the clock time is described on page
7)
3. Press the On/Off button to switch on your radio and press one of
the Preset buttons to select a station.
4. Adjust the volume using the Volume control. To switch off your
radio press the On/Offbutton.
Note:- Auto setup can take 3-4 minutes to complete and is dependent on the signal strength and number of stations in your area.
To interrupt the Auto setup press and release the Memo button.

Battery operation
1. Remove the Battery cover on the rear of the unit by pushing the
battery door in and downwards.
2. Insert two LR6 (AA size) batteries into the small spaces under flap
with yellow label. Insert four LR14 (C size) batteries into the remaining spaces in the compartment. Take care to ensure all batteries are
inserted with the correct polarity as shown inside the battery compartment. Replace the battery cover.
note : the two LR6 (AA size) batteries provide power for the
clock/memory backup and must be fitted at all times.
3. Reduced power, distortion and a ‘stuttering’ sound are all signs that
the 4 LR14 batteries may need replacing.
4. If the radio is not to be used for any extended period of time it is
recommended that the batteries are removed from the radio.
We would recommend for economy that the R9939 is used on the
mains whenever possible with battery operation for occasional or
stand-by use only.
Mains operation
1. Place your radio on a flat surface.
2. Plug the mains lead into the Socket located on the rear of your radio
ensuring that the plug is pushed fully into the socket.
3. Plug the other end of the mains lead into a wall socket and switch on
the wall socket.

Troubleshooting
Due to external interference (caused by static charges from carpets,
thunderstorms, etc.), the control electronics of your radio could receive
bad information. If the display is incomplete or the radio is not responding
to control buttons, proceed as follows:Remove the power supply (the mains and all batteries) and re-install
them again after one minute.
This resets the radio to its initial state. The stored data for the individual
memory positions, the clock, the alarm settings and the Last Station
Memory are all cleared.
General
Do not allow this radio to be exposed to water, steam or sand. Do not
leave your radio where excessive heat could cause damage such as in
a parked car where the heat from the sun can build up even though the
outside temperature may not seem too high. It is recommended that the
FM band be used wherever possible as better results in terms of quality
and freedom from interference will usually be obtained than on the MW
or LW bands.
